If you use the Mr. Bulletfeeder on a Hornady Lock-N-Load® AP™ press, you'll want one of these redesigned Powder Through Expanders (PTX™). The dimensions of the expander tip have been optimized for use with the Mr. Bullerfeeder bullet dropper.

These Powder Through Expanders are precision machined from top grade 12L14 Steel and hardened to RC55+ … offering an almost unlimited life time of use. The electro-polished finish of this part yields minimal friction and a smoother release … especially with new brass or brass that's been wet cleaned with stainless steel pins or in an ultrasonic cleaner.

Just like an original Hornady PTX™, these Powder Through Expanders are designed to work in conjunction with the Case Activated Powder Drop. They have an expander step, eliminating the need for the seperate case mouth expander die on the LNL-AP progressive press … freeing up an extra station. Some guys find it works better than the original Hornady PTX™ … even without a Mr. Bulletfeeder.
